The aim of this work was to analyse total phenolic content and resveratrol content in Thai Yadong to evaluate the quality of commercial Thai YaDong. YaDong were prepared by fermentation of ten herbal plants in white spiritual liquor and 80 % ethanol in laboratory, then total phenolic content was analysed by spectrohotometry.and resveratrol was analysed using high performance liquid chromatography. The result showed that each medicinal plant that extracted by ethanol and white spiritual liquor

The 10 medicinal plants also has an important substance as resveratrol in the range of 0.2 -7 ppm. The laboratory YaDong showed the higher value of total phenolic compound content more than commercial YaDong.The total phenolic compound content in laboratory YaDong was in the range of 62.50 -71.20 g/L, the commercial YaDong has the total phenolic compound in the range of 5.00-41.00 g/L.The resveratrol content in laboratory YaDong also showed the value as 2.00-4.20 ppm. The result proved that the commercial Yadong sold in the market contained total phenolic compound and resveratrol .
